(3) Attention:
1.The user must provide a circuit breaker or disconnect switch and fuses in accordance with all
applicable electrical codes.
2.Make sure that the leads are connected correctly and the AC drive is properly grounded.
(Ground leads should be at least the same size wire as the input leads R, S, and T.)
3.Use ground leads that comply with AWG standards. Make the length of these ground leads as
short as possible.
4.Should several AC drive units be installed side by side, all the units should be grounded directly
to the ground poles. Do not form a loop with the ground leads.
5.Make sure that the power source supplies the correct voltage and is capable of supplying the
required current to the AC drive. Refer to specification for Rated AC Input Power.Motor
Voltage should match the line voltage.
6.For single phase applications, the AC input line can be connected to any two of the three input
terminals R, S, T. A single phase DZB100B drive can be powered from three phase as well as
single phase.
Note: This drive is not intended for use with single-phase motors.
7.When the AC drive output terminals U, V, and W are connected to the motor terminals U, V, and
W, respectively, the motor will rotate counter-clockwise (viewed from the shaft of the motor as
shown below) if a forward operation command is entered (FWD lamp is ON).
